Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2023The c.703G>T (p.V235L) alteration is located in exon 9 (coding exon 9) of the EXD1 gene. This alteration results from a G to T substitution at nucleotide position 703, causing the valine (V) at amino acid position 235 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
